Laboratory Studies of Biocide and Nitrate Strategies for MIC and Reservoir Souring Mitigation
Microbicide and nitrate are applied, either alone or in combination, in many seawater injection systems as controls to mitigate microbiologically influenced corrosion (MIC) and reservoir souring. Dosing strategies vary widely from field to field. In some fields this may be due to physicochemical conditions within the injection facilities and reservoir that dictate which chemical formulations can be applied. In others the strategy might be selected based on which of the problems, MIC or souring, is assessed as the most important in terms of flow assurance. Studies were undertaken in laboratory mesocosm systems employing fixed film upflow bioreactors and recirculating biofouling rigs with flow cells to develop biofilms representing the reservoir environment and the internal metal surface of the injection system respectively. The aim of the study was to determine if similar control strategies were applicable to the mitigation of both MIC and reservoir souring.
